The ZKTeco LM‑2805 Electromagnetic Door Lock is a robust and reliable magnetic locking device designed for access control systems in offices, commercial buildings, apartments, factories, and restricted areas. It provides secure and silent door locking when integrated with access control terminals, biometric systems, RFID readers, or push‑to‑exit buttons, making it a dependable choice for modern security installations.
This electromagnetic lock features a holding force of 280 kg (approximately 600 lbs), giving strong resistance against forced entry and ensuring doors remain securely closed when locked. The lock consists of a magnet body and armature plate, which together create a powerful magnetic bond when powered. Because it operates without mechanical components, the LM‑2805 delivers near‑silent locking action and minimal wear over time.
The lock is designed for fail‑safe operation, meaning it unlocks automatically when power is turned off. This behavior is essential for safety compliance in emergency escape routes and fire exit applications where rapid egress is required during power outages. When used with an access control panel and exit button, the lock restores secure holding once power returns or authorized access is granted.
Constructed with a metal housing and corrosion‑resistant finish, the LM‑2805 is built to withstand daily use and environmental effects such as humidity. It is compatible with accessory brackets like L‑brackets and Z‑brackets (e.g., LMB‑280L, LMB‑280Z, LMB‑280ZL) for various mounting configurations — including standard, in‑swing, and glass door installations.
